TO CONNECTICUT TELEPHONE & ELECTRIC COMPANY, INC., OF MERIDEN, CON- NECTICUT, A CORPORATION OF DELAWARE TELEPHONE-INSTRUMENT SWITCHING Application filed April 29,

My invention relates generally to tele- One object is to provide a simple but compact and reliable construction which can be readily wired.

Another object is to provide a construction which is adapted to installation in various ornamental designs.

Another object is to provide a switch which is actuated either by the usual act of hanging the receiver on the hook or by the act of merely releasing or dropping the receiver.

Another object is to provide a construction which can be readily inspected and repaired.

In the preferred form I employ a housing or casing which has a front portion which carries the transmitter and the automatlc switch and signal mechanism, as shown in m former application. The back portion of the casing is adapted to be secured to the wall and carries the circuit terminals and connections leading to the instrument. The two parts of the casing are provided with plug-in blades for convenience in connection and installation as set forth and claimed in my former application.

The front part of the casing is preferably formed of insulating material and provided with a rearwardly extending boss which supports the spring contacts of the switch and some of the circuit terminals. The switch actuating lever is pivoted on a tubular stud mounted on the front of the casing. This stud has a slotted end for receiving the loop of the telephone receiver at the proper position to engage the front end of the switch lever. An auxiliary lever is pivoted within the casing and has one end connected with 1929. Serial No. 359,124.

the switch lever and the other end connected with the receiver cord, so that the weight of the receiver can be employed to hold the switch in the normally active position, whether the receiver is properly hung on the hook or simply left hanging.

The details of the construction will be understood from the following specification:

Fig. 1 is a rear view of such parts of the instrument as embody the improvements of the invention claimed herein.

Fig. 2 is a vertical transverse sectional view of the same but also shows a fragment of the back plate or wall plate.

Fig. 3 is a horizontal section or plan view.

Fig. 4 is a fragmentary vertical sectional view showing the parts of the casing which support the switch and switch lever.

Fig. 5 is a side view of the tubular stud and switch lever carried thereby.

The front member 10 of the casing may be of any suitable design and formed of any suitable material, preferably insulating.

The back plate 11 is adapted to be secured to the Wall. The front plate is'providcd with a peripheral flange 12 and the parts are preferably hold together by screws and telescopic members 13.

At the back of the front wall is a ledge 14 on which is mounted a number of terminals and plug-in blade members such as 15 adapted to'engage cooperating stationary sockets carried by the back plate. A terminal plate, such as 16, may also be secured to this ledge 14 for effecting various electrical connections.

The pedestal or boss -17 projecting rearwardly from the front wall of the casing serves to support spring contact fingers, such as 18, 19, 20 and 21 of the usual type. Screw threaded sockets 22 are preferably bedded in the boss 17 to receive the screws 23 which support the contact fingers. The boss 17 has a groove 24 and the spring contact fingers are mounted in this groove and project toward the center of the casing. This serves as a very convenient method of attaching the contact fingers. The groove divides the pedestal into two parts and one pair of contact fingers is supported on each boss. Electrical connections preferably in the form of flat strips 25 are connected to the switch contacts by screws 23, etc.

The switch operating lever 26 is pivoted on the pin 27 within the tubular stud 28. A spring 29 wound on the pin 27 tends to lift the outer end of the lever 26. This stud 28 passes through the front plate 10 and is secured in place by a nut 30 which may also serve to support other elements (not shown). The front wall .is provided with a hole 31 through which the shank of the stud 28 extends and recesses 31' are provided to receive the ends of the pivot pin 27 so as to prevent the stud from turning on the front plate.

The receiver 32 of any suitable type is provided with a loop or eye member 33 adapted to be hung onto the front end of the lever 26. The stud 28 is provided with a shield member 34 which protects the other end of the switch actuating lever and leaves a slot 28' which serves to hold the receiver in place. The cord 35 of the receiver extends through a passage 12 and has its terminals 36 and 37 secured to the proper terminal pieces in the casing.

An auxiliary lever 38 is provided on the post 39 in the casing and has one end forked to engage the switch lever 26. The other end of the lever 38 is connected by a he 41 to the receiver cord, so that when the weight of the receiver pulls on the cord, the lever 38 is tilted to the position shown in Figs. 1 and 2, which is the same that it occupies when the receiver hangs on the hook in the usual manner. The stud 12 serves as a stop for the lever 38 when the weight of the receiver is on it.

It will be seen that the switch actuating lever 26 and spring 29 and pin 27 may be assembled in the stud 28 so that these parts may be handled as a unit in the assembling of the construction.

It will be seen that the switch contacts and operating parts and connections are all exposed and readily accessible when the rear plate of the casing is removed.

Various changes in details of construction may be made without departing from the principle of the invention.
